Shaver with improved hair setup

ABSTRACT

A shaver for hair which includes a hair setup part positioned adjacent the cutter of the shaver. The setup part includes a plurality of uniformly spaced diagonally extending grooves positioned in front of the cutter of the shaver which contact the skin of the shaver user and cause the hair thereon to be lifted up in the path of shaver movement with a resulting closer and smoother shave.

8 Claims, 4 Drawing Figures PATENTEDJUL 4 1972 v INVENTOR. F/PANK FMUNTZ GMEMM ATTORNEYS SHAVER WITH IMPROVED HAIR SETUP SUMMARY OF THEINVENTION This invention pertains to a shaver for hair which includes animproved hair setup part and which will have specific application toelectric shavers.

The shaver of this invention will include a power driven hair cutter, ahair setup part, and means supporting the hair setup part adjacentlyforwardly of the cutter in the path of cutting movement of the shaver.The setup part includes an outer skin-contacting surface which isinterrupted by a plurality of spaced grooves. The grooves in the setuppart extend obliquely to the path of cutting movement of the shaver.This invention relates to an improvement to my shaver described in US.Pat. No. 2,725,625 and provides for a smoother, more comfortable shave.The diagonally grooved hair setup part incorporated into the shaver ofmy invention causes the skin on the face or leg of the shaver user to bepulled laterally relative to the direction of cutting movement of theshaver and the hair thereon to be lifted up and positioned forengagement with the cutter. The prior art shavers with hair setupdevices, such as those found in US. Pat. Nos. 2,343,705; 2,670,534; and3,148,447 and of which I am aware, do not provide for such lateralmovement of the skin and the uplifting of the hair in preparation forcutting.

Accordingly, it is an object of this invention to provide a shaver forhair having means incorporated therein which causes the hair to belifted up in preparation for cutting.

Another object of this invention is to provide an electric shaver forthe face or legs which provides a close, comfortable and smooth shave.

Still another object of this invention is to provide a shaver for hairincorporating a hair setup part which does not irritate the skin of theshaver user.

Other objects of this invention will become apparent upon a reading ofthe invention s description.

BRIEF DESCRIPTION OF THE DRAWINGS A preferred embodiment of thisinvention has been chosen for purposes of illustration and descriptionwherein:

FIG. 1 is a perspective view of a shaver which includes my hair setuppart.

FIG. 2 is a fragmentary enlarged cross sectional view of the shavertaken along line 22 of FIG. 1.

FIG. 3 is a perspective view of the hair setup part utilized in theshaver of FIG. 1.

FIG. 4 is a longitudinal sectional view taken along line 4-4 of FIG. 3.

DESCRIPTION OF THE PREFERRED EMBODIMENT The preferred embodimentillustrated is not intended to be exhaustive or to limit the inventionto the precise form disclosed. It is chosen and described in order tobest explain the principles of the invention and its application andpractical use to thereby enable others skilled in the art to bestutilize the invention.

The shaver illustrated in FIG. 1 includes a housing 12 having a headportion 14. Head portion 14 of shaver 10 carries two laterally spacedparallel cutters 16 each cutter having two parallel cutting sides. Eachcutter 16 includes a reticulated screen part 18 which is secured to headportion 14 and a blade part 20 which is positioned within screen part 18and which is adapted for oscillatory movement relative to the screenpart. Each blade part 20 of cutter I6 is connected by an actuating pin22 to a suitable drive means, such an an electric motor setup part 24 ispositioned in approximately the same plane as outer surfaces 30 ofcutter parts 18 and is interrupted by a plurality of grooves 28. Grooves28 extend obliquely between cutters l6 and are preferably spaced anequal distance apart. Grooves 28 are of uniform shape and dimension witheach groove having a width preferably between one forty-eighth andone-sixteenth of an inch and a depth of at least one sixtyfourth inch topermit portions of the skin of the shaver user to enter the groovesduring use of the shaver. The spacing between grooves 28 is preferablybetween one-eighth and three-sixteenths inch with the angle of thegrooves being preferably between 30 and 60 relative to the length of thesetup part. Set up part 24 may be formed of rubber, plastic or metalwith grooves 28 therein having a square, arcuate or V- shapedcross-sectional configuration. The upper edges 32 of each groove 28 arepreferably slightly rounded to avoid sharp edges in the outer surface 27of the setup part which, if present, could cause irritation of the skinof the shaver user. Setup part 24 is supported between cutters 16 bypartition part 34 of shaver head portion 14. Setup part 24 may beretained upon shaver partition part 34 by being press fitted betweencutters 16 or by the use of an adhesive or similar type of bonding agentwhich secures the setup part to the partition part.

As shaver 10 is moved back and forth in the direction of double-headedarrow 36 in FIG. I, outer surface 27 of setup part 24 makes contact withthe skin of the user of the shaver and causes the skin to protrude intothe grooves and to be pulled generally laterally relative to the path ofmovement of the shaver, thus causing the hairs on the skin to be liftedup.

Setup part 24 can be applied to shavers of various constructions, suchas shavers having a single cutter-in which case the setup part would bepositioned in front of the cutter, or such as shavers having three ormore parallel rows of cutters-in which case a setup part 24 would belocated between adjacent rows of cutters. In a shaver which includes asingle elongated cutter having two longitudinal cutting sides, a setuppart 24 could be located on each such side of the cutter so that one ofthe setup parts would always be in the path of cutting movement of theshaver as it is moved up and down or back and forth across the face, legor other parts of the body of the shaver user.

It is to be understood that the invention is not to be limited to thedetails above given but may be modified within the scope of the appendedclaims.
